ANVIL F0 SPECIFICATION forming part of Letters R LATHES.

Patent No. 303,976, dated August 26, 1884.

Application filed November 9, 1383. (No model.)

To all whom it may concern:

Be it known that I, J OHN BIRKENHEAD, of ldanstield, in the county of Bristol, of the Cornmonwealth of Massachusetts, have invented a new and useful lathe anvil or device for supporting an article or piece of work for detaching from or fixing thereto an arbor or spindle; and I do hereby declare the same to be described in the following specification, and represented in the accompanying drawings, of which Figure 1 is a top view, Fig. 2 a front elevation, Fig. 3 a vertical and longitudinal section, and Fig. 4c ahorizontal and transverse section, of it.

The said device is a new manufacture or article for use by and convenience of tnrners, and is intended to be set up near a lathe.

The nature of the invention is defined in theclaims hereinafter presented.

The article I term a lathe-anvil, in order to distinguish it from ordinary a-nvils used by smiths. I

In the drawings, A denotes a furcated or angularly-notclred head, the notch or crotch of which shown at a. The said head is supported on a stand, B, similarly recessed, as shown at I), and provided ator near its middle with a transverse brace or partition, 0. The drawings show the article as having two notched heads, A and A, the lower one, A, being in construction like the upper one, A; but instead of the said lower head a simple partition extending across the stand may be employed and serve as a foot or base for supporting it. Each head,in rear of the vertex of its angular notch, has an open chamber, (1, in it, containing a filling, c, of lead or other propor soft metal, there being extended from the bottom of the chamber and through the head a hole, f, to enable such metal in a molten state to be run into the chamber, when the an vil is inverted, and may rest on a flat surface. The brace answers as a shelf for supporting a hammer or other device or devices.

To use the anvil, we will suppose that a wheel or other article is to be detached from an arbor going through it axially; we have only to place the arbor closely up within the crotch of the head A, with the wheel or piece head. In this state of things the arbor may be driven out of the wheel or piece of work by a hammer or tool struck on the upper end of it. (the said arbor.) So, while a wheel or piece of work may be on the head, an arbor may be inserted and driven into such wheel or piece of work. In either case this may be effected without first requiring the removal of a dog when fixed on the arbor, and for use in alathe for preventing the arbor from revolving independently of the rotary spindle of such lathe.

The said latheanvil is to be made of cast iron, and its head should be plated with steel or be chill-hardened, to prevent it from being injured by the work. The block of soft metal inserted in the head is to enable an arbor to be detached from a piece of work by striking the arbor, end downward, upon the said block. Vere the arbor struck on the face of the head, the end of the arbor would be liable to be injured thereby.

I claim- 1. The described lathe-anvil, consisting of the furcated or notched head or heads and the recessed stand extending therefrom, as set forth.

2. The lathe-anvil consisting of the furcated or notched head or heads and the recessed stand extending therefrom, and provided with the transverse brace arranged in it, as set forth.

3. Thelatheanvil consisting of thefurcatcd or notched head or heads, and the recessed stand extending therefrom, and of the block ol'sot't metal inserted in one or each of such heads, all being substantially and for use as represented.
